Back Mix System for Fluid Bed Dryers: The back mix system is used for materials that can not fluidise due to the high moisture content of the material.
Sticky material, wetcake from the filter press, slurry, sludge or even a solution is mixed with dried product. This back mix flow enables better fluidisation and drying. The fluid bed dryer dries the material at low temperatures and uses the waste heat available to ensure optimum use of heat energy. The high speed of the process and controlled temperature ensure the optimum efficiency of the process. Dried product has a longer shelf life and reduces transport costs.
